Application January 15, 1954, Serial No. 404,277 2 Claims. Cl. 24265)This invention relates to a means for continuously winding rolls ofmaterial and has for an object to provide means for changing the windingmaterial from a completed roll to a fresh roll without interruption insupply or change of speed in the winding material.

Many forms of machines are adaptable to produce and operate on acontinuous web. Such machinery will naturally discharge the web in acontinuous operation. In order that the web may be wound and practicablequantity upon separate reel it is necessary to discontinue the windingupon a reel which has received a predetermined quantity and to initiateWinding upon an empty reel without stopping the continuous operation ofthe web producing or treating machinery. For example, in the paperindustry a paper making machine produces a continuous web of paper andunder ideal conditions a machine will not be shut down for several days.Similarly, paper coating machines are more efficiently run in acontinuous manner and to this end paper may be supplied to them from asuccession of reels which are so handled so as to splice the leading endof the uncoated paper to the trail-v ing end of the spent reel. Thesesplices may be made by any of the well known flying slice mechanisms andunless it is necessary to stop the machine for purpose of change. ofreels, the coating operation may be continuously performed in either ofthese examples as Well as in any other instance. It is highly desirableto provide instantaneous transfer of the web from one winding reel toanother.

Various types of reeling devices are known which are capable of handlinga continuous moving web. One widely used form is known throughout thepaper industry as the-Pope reel. Such a reel is shown in United StatesPatent No. 1,248,542. The present invention is particularly adaptablefor use in conjunction with the Pope reel although, obviously, it is notlimited in its use to such reel. For the purpose of description theinvention will be set forth in connection with the Pope reel.

In general the Pope reel comprises a driving drum which is rotated at aperipherial speed equal to the speed of movement of the web with whichit is to be used. Empty reels are placed into frictional contact withthe surface of the driving drum and the leading end of the paper issecured in some manner to the empty reel whereby rotation of the drivingdrum will serve to rotate the empty reel and wind the paper therearound.When a predetermined quantity of paper has been wound upon the reel, itis necessary to shift the filled reel while it continues to wind to aposition permitting the insertion of a new empty reel.

At this time the web is severed along a line just beyond the empty reeland the leading edge thus formed is directed upwardly around the emptyreel. The directing of the web may be accomplished by the use of jets ofair or water or steam, or may be accomplished by some mechanicalmanipulation or even by manual manipulation. Assuming a manualmanipulation, the leading edge is gripped by the operators at oppositesides of the machine and thrown up and over the empty reel whereby theleading edge drops down upon the face of the paper progressing towardthe reel. This serves to drag the leading edge into the nip between thewinding reel and the driving drum and forms a bight having sufiicientfriction to secure the web to the winding reel. From this point on theweb the paper will be progressively wound upon the reel.

At an appropriate time the partially wound reel may be moved along theperiphery in the direction of rotation thereof and brought to rest in asuitable bearing mechanism wherein it continues to wind in order toaccumulate the predetermined quantity of web material. In the meantime anew empty reel is brought into position and is suspended just above thedriving drum in a position ahead of the reel upon which the web is beingwound. When the predetermined quantity is reached, it is necessary tosever the web at a point between the empty reel and the filled reel andit is necessary to direct the leading edge of the web around the emptyreel to initiate winding upon the same.

' The usual steel roll used as empty reels has been replaced by a rubbercovered roll. The rubber covered roll has many advantages among which isno scoring or marking of reel drum surface. When the empty is loweredonto rotating reel drum, the friction often breaks the web. This webbreaking results in considerable loss of paper.

Accordingly, it is an object of this invention to provide means forbringing the empty reel to substantially the same peripherial speed asthat of the driven reel drum.

Other and further objects of the invention and the advantages of thesame will be pointed out hereinafter and indicated in the appendedclaims or will be obvious to one skilled in the art upon understandingthe present disclosure.

While one embodiment of the invention has been described in more or lessdetail to comply with the requirement of the statute, it is neverthelessdesired that the detailed description be considered merely asillustrative and not as limiting.

in the drawings wherein similar parts are identified from similarcharacters of reference throughout the views Figure 1 is an end viewwith parts broken away of a winding device embodying the presentinvention and Figure 2 is a side view of the apparatus shown in Figure 1with portions broken away.

The apparatus herein shown comprises a more or less conventional windingdrum which is suitably rotatably mounted through the agency of a shaftsuch as indicated at 12 which extends from its opposite ends. A paperWeb 14 which is being delivered from a paper making, calendering orother paper treating apparatus is delivered over said winding drum 10and is wound upon the reel core 15 (similar to that shown in Patent No.1,925,670) to form a reel of paper. The reel core having paper woundtherearound is, of course, suitably supported as to maintain thecircumference of the paper being wound thereon in engagement with thewinding drum 10 in accordance with more or less common practice.

While one reel is being formed another rubber covered reel core 16 issuitably positioned above the paper web 14 and adjacent the winding drum1%. The core reel 16 is provided with shafts 18 extending from oppositeends thereof. Member 30 is mounted on shaft 1% upon which is suitablymounted reel coupling 22. The reel core 16 is supported by reel bearingblock 24. This block is shown in Figure 1 and such a block has performedhighly successfully in operation. The block 24 is supported by member 26which is carried by frame member 28. Mounted on shaft 12 and adapted torotate therewith is belt sheave 30. Supported by member 36 adjacent itsupper end is a three grooved sheave 32. The sheave 32 is rotatablymounted upon suitable shaft 34 which is carried ber 40. The distancebetween the sheave 32 and the sheave 44 can be varied according to theneed. The arm has extending therefrom shaft 42 which rotatably carriesthe sheave 44. Connected to the arm 38 at 46 is air cylinder piston rod48. This piston rod is operatively mounted in air cylinder 50. One endof the air cylinder 5' is hingedly, connected to clevis 52at Air lines56 supply air to cylinder 50 and these air lines have mounted thereinair flow control valves 53 and a four-way air cylinder valve 6 3. Theair cylinder valves 61 have connected thereto air supply line 62 andexhaust port 64. The sheave 30 is adapted to drive by suitable meanssuch as V-belt 66, the sheave 32 which in turn rotates sheave 40 throughthe medium of V-belts 68 and 70.

When the reel core 16 is in position shown in Figures 1 and 2, thesheave 44 and the V-belts 6S and 70 are in the position shown in dottedlines in Figure 1. When core has received approximately thepredetermined amount of paper and the paper isto be changed to a newreel core, the reel core 16 is brought up to substantially the sameperipherial speed as the reel drum it This is accomplished by forcingthe V-belts 68 and 70 into contact with reel coupling surfaces 22. Thesheave 38 being driven by the shaft 12 imparts substantially the samespeed of the wind drum to the reel core 16. When the paper is to bestarted upon the reel 16, this reel is lowered to the surface of thecylinder drum 10 by tilting the yoke 72 in the direction of the rotationof the drum '10. The, reel bearing slides ed the block 24 when the yoke70 is tilted. The yoke '78 may be supported by the shaft 12 by member 74 and have yoke receiving block 7 6 mounted on shaft 18. To move thebelts 68 and 70 from the position shown in dotted lines, Figure 1, airis admitted to the air cylinder 50 and the rod 48 is forced outwardlybringing the rotating belts into operating contact with the reelcoupling surface.

It is to be understood that the V-belts may be replaced by any suitabledriving means but V-belts have proven highly successful and economicalin operation.

Typical of terms which may be applied to means upon which the paper isto be wound are the following reel, reel core, spool, mandril orspindle. The particular expression used in the specification is to beread as applying to any such members or to all of them.
